Genes affected

CD27 (HGNC:11922): (CD27 molecule) The protein encoded by this gene is a member of the TNF-receptor superfamily. This receptor is required for generation and long-term maintenance of T cell immunity. It binds to ligand CD70, and plays a key role in regulating B-cell activation and immunoglobulin synthesis. This receptor transduces signals that lead to the activation of NF-kappaB and MAPK8/JNK. Adaptor proteins TRAF2 and TRAF5 have been shown to mediate the signaling process of this receptor. CD27-binding protein (SIVA), a proapoptotic protein, can bind to this receptor and is thought to play an important role in the apoptosis induced by this receptor. [provided by RefSeq, Jul 2008]

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

ClinVar contains an entry for this variant (Variation ID: 540910). This variant has not been reported in the literature in individuals affected with CD27-related conditions. This variant is present in population databases (rs779092602, gnomAD 0.0009%). This sequence change creates a premature translational stop signal (p.Gln181*) in the CD27 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in CD27 are known to be pathogenic (PMID: 25843314). For these reasons, this variant has been classified as Pathogenic. -
